Objective To evaluate the value of health intervention to changeable risk factors in persons with diabetes prophase.Methods One hundred and eighteen persons in diabetes prophase were divided into two groups randomly.For 58 persons enrolled in the experimental group,health intervention including lectures of diabetes basic knowledge,introducing the necessity and significance of periodical check up and examination,suitable dietary and nutrition,weight control,physical exercise and movement was performed.For 60 persons enrolled in the control group,only the diagnosis of diabetes prophase was informed.The incidence of normalization of blood glucose and progressing to dominant diabetes was compared between the experimental group and the control group after follow-up for 6 months and 12 months.Results After 6 months of intervention,the difference of the number of persons was not significant for normalization of blood glucose between experimental group and control group(x2=0.04 and 0.79,P=0.84 and 0.12 for persons with IFG and IGT respectively),and was also not significant for progressing to dominant diabetes between the two groups(x2=0.96,P=0.33).After 12 months of intervention,the difference of the number of persons was significant for normalization of blood glucose between experimental group and control group(x2=13.34 and 22.58,P<0.01 and<0.01 for persons with IFG and IGT respectively),but still not significant for progressing to dominant diabetes between the two groups(x2=2.83,P=0.09).Conclusions The intervention to changeable risk factors can prevent or delay the occurrence of diabetes mellitus,and improve the quality of life for person with diabetes prophase.

PURPOSE: It is widely accepted that aldehyde dehydrogenase (ALDH) activity is a signature of breast cancer stem cells, and high activity has been reported to be associated with poor clinical outcome. The aim of this study was to assess the expression of members of the ALDH family of isozymes in breast cancer tissues and to evaluate the implications of the results. METHODS: We analyzed paraffin-embedded tumor tissue from 160 patients with breast cancer. Immunohistochemistry (IHC) staining was performed on the slides using antibodies against different ALDH family members. We collated the IHC results with patient clinical characteristics and determined their prognostic value. In addition, we analyzed normal, hyperplastic, and carcinomatous tissues in situ to check their ALDH distributions. RESULTS: All the tested ALDH members were detected in the various tissue types, but at different levels. Only ALDH 1A3 was found to be significantly associated with distant metastasis (p=0.001), disease-free survival (p<0.001), and overall survival (p<0.001). CONCLUSION: The level of ALDH 1A3 in breast cancer tissue is a predictive marker of a poor clinical outcome.

Primary ureteral plasmacytoid carcinomas is a rare tumor with high grade and poor diagnosis. Pathological and immunohistochemical staining play an extremely key role in diagnosis since there is no specific clinical and radiological evidence. The surgical removement is the first line treatment. Herein, we report a case of ureteral plasmacytoid carcinoma that was well controlled with multimodal therapy.

Translationally controlled tumor proteins (TCTP) and SNF1- related protein kinase (SnRK1) are conserved and widely present in eukaryotic cells. TCTP regulates cell division, plant growth and development, and mediates plant resistance against pathogen infection. SnRK1 participates in a range of physiological processes including sugar metabolism and resistance to abiotic and biotic stresses. Previous work in our laboratory demonstrated that wheat TCTP can respond to Puccinia triticina infection and induce host defense responses. In order to further investigate the mechanism of TaTCTP in wheat resistance to Puccinia triticina infection, we used TAP (tandem affinity purification) and mass spectrometry to screen the potential interactants of TaTCTP. A SNF1- related protein kinase (SnRK1) was identified as a potential interacting protein of TaTCTP. The results of yeast two-hybrid assay showed that TCTP could interact with SnRK1 in yeast, and the yeast carrying TCTP and SnRK1 could grow on SD/-Leu/-Trp/-His/-Ade (SD/-LWHA) medium. The fluorescence signal of the interaction between TCTP and SnRK1 was found to be distributed in the cytoplasm in the Bi-fluorescense complementation experiment. Co-IP experiments further showed that TCTP and SnRK1 could interact in plant cells. This study lays an important foundation for further studying the mechanism of TaTCTP in the interaction between wheat and Puccinia triticina, and it play a great influence on further improving the molecular mechanism of wheat resistant to Puccinia triticina.

Mitochondrial diseases are maternally inherited heterogeneous disorders that are primarily caused by mitochondrial DNA (mtDNA) mutations. Depending on the ratio of mutant to wild-type mtDNA, known as heteroplasmy, mitochondrial defects can result in a wide spectrum of clinical manifestations. Mitochondria-targeted endonucleases provide an alternative avenue for treating mitochondrial disorders via targeted destruction of the mutant mtDNA and induction of heteroplasmic shifting. Here, we generated mitochondrial disease patient-specific induced pluripotent stem cells (MiPSCs) that harbored a high proportion of m.3243A>G mtDNA mutations and caused mitochondrial encephalomyopathy and stroke-like episodes (MELAS). We engineered mitochondrial-targeted transcription activator-like effector nucleases (mitoTALENs) and successfully eliminated the m.3243A>G mutation in MiPSCs. Off-target mutagenesis was not detected in the targeted MiPSC clones. Utilizing a dual fluorescence iPSC reporter cell line expressing a 3243G mutant mtDNA sequence in the nuclear genome, mitoTALENs displayed a significantly limited ability to target the nuclear genome compared with nuclear-localized TALENs. Moreover, genetically rescued MiPSCs displayed normal mitochondrial respiration and energy production. Moreover, neuronal progenitor cells differentiated from the rescued MiPSCs also demonstrated normal metabolic profiles. Furthermore, we successfully achieved reduction in the human m.3243A>G mtDNA mutation in porcine oocytes via injection of mitoTALEN mRNA. Our study shows the great potential for using mitoTALENs for specific targeting of mutant mtDNA both in iPSCs and mammalian oocytes, which not only provides a new avenue for studying mitochondrial biology and disease but also suggests a potential therapeutic approach for the treatment of mitochondrial disease, as well as the prevention of germline transmission of mutant mtDNA.
